FABRroA'rnn SHOE sone. l

The object of my present invention,.broad ly speaking, 1s to provide afabricated shoesole of simple and vdurable construction,

which will be neat and artistic in appear- ,out thje several views.

ance, which will be easy and comfortable on the feet of the wearer, andwhich can be manufactured and sold at a comparatively low price.. i Morespecifically stated, rmy object is to m provide a shoe-sole composedOf-rubber. and

fabric, thereby lessening the cost of manufacture by reducing the amountofv rubber*v therennand at the same time making the sole of greaterdurability and more comfort- F able to ones feet when in use.`

Still more specifically stated, my object is to provide a vshoe-soleformed of alternate layers of rubber and fabric securely vulcanizedtogether, with which is incorporated means for making the strands offabric of comparatively short length whereby the cords of fabric willnot frazzle or run, and thereby producing asole in which the fabricwillhave a greater length of life, and also the intermediate layers ofrubber will be integrally united with each other at frequent ypointsthroughout the extent, of the sole. And, finally, my object is not'aloneto produce a shoe-sole constructedsubstantially as herein set forth, butto produce Ithe same by a new and novel process, which will be fullyexplained herein.

Other minor objects and particular advantages of my invention willsuggest themselves in the course of the following description and thatwhichis'new will be correlated in the appended claim.

The specific means for carrying out the objects of this invention in apractical man ner is shown in the accompanying drawings, in which" lFigure 1 is an inner-face plan view of the core or fabricated body of myshoe-sole, showing it prior to the application of the outer facesthereof. Figure 2 is a plan view of my finished shoe-soleas itwouldappear on either its upper or lower sides. Figure 3 is a crosssection of the completed shoe-sole, as taken on the line 3-3 of Fig. 2and on an enlarged scale. And Figure 4 is a plan providing means wherebythe two outer and view, ythe same as Fig.1,-except that the aperturesformed therethrough are .different from that shown inFig. l. f' ASimilar ndices denote like parts through- In order that theconstruction,- the process of construction, andi the .several advantagesof my invention may bevmore vfully understood and appreciated, I willnow take up a detailed description thereof, in which I will setforth thesame as fully as :I can.

Referring now to my invention` in detail:

The body` of my shoe-sole comprises a plurality of layers of fabric, asfor instance the layers y1, 2, 3, l` and 5, which aresuperimcomparatively thin layer of rubber 6, or its equivalent, disposedbetween each two layers of fabric. f

The outer upper edges formed by the com` bined layers of fabric andrubber are cham- `posed with relation to each other, with a as shown inFigs. l and 3 are attached tightly together, either by cement or byvuilcanization, or otherwise, whereby they are all practically integralwith leach other. A plurality of apertures 7, as in Figs. 1 and 3, or.slots 8,. as in Fig. 4, are thenCut through the body thus formed, whichare for the two Vmain purposes hereinafter set forth. Said apertures 7or 8 are preferably formed only in the forward half of the sole, that istoA say no apertures are forme'd through the heel Or the shank portionof the sole, although 'they may also be provided withcorresponding'apertures if desired.

After the body portion has been provided with apertures, as above setforth, then the entire body is to be covered with a layer of rubber, orthe like, with the same filling all of said apertures 7 or 8, therebyintegrally uniting the top layer 9 with the bottom layer body andbringing the periphery thereof out square, that is at substantiallyright-angles to the layers 9 and 10, as well as to the fabric, asindicated in Figs. 2 and 3, or it may re main beveled, as in Fig. l.

The purpose of the apertures 7, and 8, is two-foldz The main purpose isto cut the cords of the fabric whereby they will each be ofcomparatively short length. rlhis results in longer wear for the soleand affords greater elasticity thereto, and it also prevents the fabricfrom breaking and frazzling by usage. The second purpose of saidapcrtures is to provide m-eans whereby the layers 9 and l() of therubber will be integrally united at frequent intervals throughout theforward portion of the sole, thereby preventing the layers of rubberfrom becoming detached from the body of the sole by prolonged usagethereof.

After the outside rubber, including the layers 9 and 10, has beenapplied then the whole should be vulcanized, thereby forming the solesubstantially as shown in Fig. 2, with the fabric parts completelyenclosed by the rubber parts.

As shown in Fig. 21the sole when completed has the appearance of asolid-rubber sole, however in fact it will be cheaper in construction,but .more especially it will be more durable, more comfortable to wear,and will otherwise carry out the objects above enumerated.

The process of forming my shoe sole consists in providing a plurality oflayers of fabric or cords, with each layer formed of a contour such asto simulate the bottom of a human foot, with said layers correspondingwith each other in contour, superimposed upon each other, and decreasingin size from the bottom to the top layer, each consisting of a heelportion, a shank portion, and a forward portion, commonly called thehalf-sole. The process further consists in placing thin layers of rubberbetween each two layers of fabric, and then cementing or Vulcanizing therubber and fabric together, thereby forming the body of the sole.v Thenext operation is to form a plurality of apertures or slots through theforward portion, or half-sole, the same being Leveeeo so located as toseparate the threads or cords of the fabric into comparatively shortlengths.

I next cover the body so formed with rubber, both above and below,filling said apertures or slots with the rubber, covering the edges ofthe fabric and filling in the bevel formed around the periphery of thebody and providing a square vertical or beveled edge on the completedsole. And finally the rubber last applied is vulcanized into connectionwith the body whereby I provide a practically integral and unitarystructure, forming a. complete sole, appearing substantially as shown inFig. 2.

In some instances it may be desirable 'to build my shoe-sole with butone layer of fabric, thereby emittino' the layers of rubber 6, butotherwise forming the sole as above set forth.

I also would have it understood that I am not to be limited to the useof rubber in the construction set forth, an artificial rubber, or acomposition, or otherequivalent, may be employed. i

I desire that it be understood that various changes may be made in theseveral details herein set forth without departing from the spirit of myinvention and without sacrificing any of the advantages thereof whichare new and useful.

Having now fully shown and described my invention, what I claim, anddesire to secure by Letters Patent of the y United States is, y

A. shoe sole comprising a laminated body formed with heel and soleportions and made up of alternate superposed layers of differentmaterials, said materials being formed to provide a relatively integralmass, the sole portion of said bodyk being formed with openingsextending completely through the layers and the edges of the body beingchamfered, and an inherently resilient material molded about the body toform square edges thereon, to completely envelope the body, and toextend through the openings therein to provide a substantiallyhomogeneous mass.
